Step-by-step explanation:
The soil for house plants consists of 12% water. If someone wants to plant flowers
that need 28% water in the soil, how many liters of water they need to add to 5 kg of
soil?
The liters of water they need to add to 5 kg of soil is equal to
3.66 dl water.
We have given,
Anna bought soil that contains 12% of water.
She wants to plant a flower that needs 18% of water.
We have to determine, how much water does she need to pour in 5 kg of soil to plant the flower
Now, anna bought soil that contains 12% of water
5 kg of soil
Water = (12/100)2 = 0.6 kg
Let Water poured = W kg or liter
What is the total water?The addition of the amount of all water given in the question.
Therefore we get,
Total Water = 0.6 + W kg
Total Soil = 5 + W kg
18% of water
(18/100)(5 + W) = 0.6 + W
90 + 18W = 60 + 100W
30 = 82W
W = 30/82
W = 0.366 kg or 0.366 litre
or 3.66 dl
The liters of water they need to add to 5 kg of
soil is equal to 3.66 dl water.

Timmy is helping his grandpa on his chicken farm. Timmy has to pack 66 eggs into cartons, minimizing the packing cost. He can use 12-egg cartons and 6-egg cartons. Two 12-egg cartons cost as much as three 6-egg cartons.
The way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.
Since Timmy is helping his grandpa on his chicken farm, and he has to pack 66 eggs into cartons, minimizing the packing cost, and he can use 12-egg cartons and 6-egg cartons, and two 12-egg cartons cost as much as three 6-egg cartons, to determine how many cartons of each should be used, the following calculation must be performed:
2 x 12 = 3 x 6 24 = 18 Thus, assuming as an example that a total of 2 cartons of 12 eggs and 3 cartons of 6 eggs cost $ 3, the value of each carton would be the following: 3/3 = 1 3/2 = 1.5 66/12 = 5.5 5 x 1.5 + 1 x 1 = X 7.5 + 1 = X 8.5 = X
In this way, the way to distribute the eggs at the lowest cost would be using 5 cartons of 12 eggs and 1 carton of 6 eggs.

If g(x)=3x-2, find g(3)-g(-8)
Answer:
33
Step-by-step explanation:
1. Let's solve for g(3)
Step 1: Plug in the value of x.
[tex]g(3)=3(3)-2[/tex]Step 2: Simplify.
[tex]g(3)=9-2[/tex] [tex]g(3)=7[/tex]2. Let's solve for g(-8)
Step 1: Plug in the value of x.
[tex]g(-8) = 3(-8)-2[/tex]Step 2: Simplify.
[tex]g(-8) = -24 - 2[/tex] [tex]g(-8)=-26[/tex]3. Now, let's subtract g(-8) from g(3).
[tex]g(3)-g(-8)[/tex] [tex](7)-(-26)[/tex] [tex]7+26[/tex] [tex]33[/tex]Therefore, the answer is 33.
Answer:
33
Step-by-step explanation:
g(x) = 3x - 2
g(3) = when x of g(x) function is 3.
g(3) = 3(3) - 2
g(3) = 9 - 2
g(3) = 7
g(-8) = 3(-8) - 2
g(-8) = -24 - 2
g(-8) = -26
g(3) - g(-8)
7 - (-26) = 33
A glass container can hold 216a^3 cubic cm of water. inside the glass container is a metallic cube with a volume of 64b^3 cubic cm. How much water you will be able to fill the glass container with the metallic cube inside? Express your answer in factored form.
Answer:
[tex]16(3a-2b)(4a^2+3ab+2b)[/tex]
Step-by-step explanation:
We will be able to fill the glass up to the amount of water possible to hold in the glass, minus the amount in the cube. This means it will be able to hold [tex]216a^3-64b^3=(6a)^3-(4b)^3[/tex]cubic cm of water.
Using the difference of cubes formula(you can prove this by expanding back out again), we get that [tex](6a^3)-(4b)^3=(6a-4b)((6a)^2+(6a)(4b)+(4b)^2)=(6a-4b)(36a^2+24ab+16b)=8(6a-4b)(4a^2+3ab+2b)=16(3a-2b)(4a^2+3ab+2b)[/tex]
Therefore, the answer is [tex]\boxed{16(3a-2b)(4a^2+3ab+2b)}[/tex] cubic centimeters and we're done!

Answer:
(A) -4 and -2
Step-by-step explanation:
The constant in the function tells you f(0) = 5.
You know that the positive leading coefficient means the value of f(x) will be negative for x-values smaller than some number. The offered answer choices indicate the value x = -4 is a lower bound on the value of c. So, -4 < c < 0, for sure.
To further refine the interval, you would need to know f(-2) and/or f(-1).
f(-2) = (-2)³ -2(-2) +5 = -8 +4 +5 = 1
Then -4 < c < -2.
